FIELD: electric engineering, possible use in automatic devices for commutation of electric circuits with 1,5-2 times increased maximal allowed power level.
SUBSTANCE: in accordance to the invention, magnetically controlled contact contains a glass tank, in ends of which two identical ferromagnetic contact parts are installed, having several spreading sections of varying thickness, symmetrical relatively to longitudinal axis of contact part. Free ends of contact parts form a gap and overlapping aH. Value hH of thickening on free end of contact part to round part of output of diameter d is limited by inequality 
. Ratio of geometrical dimensions of maximal thickening of ends of contact parts in their overlapping zone "aH" is limited by inequality 
, where lH - the length of maximal thickening on the free end.
EFFECT: extended commutation ability of magnetically operated sealed switch and stabilization of contact resistance.
